You probably have to set it up with a Google account to make the market work. Go to settings -> accounts and add your gmail account, or create one if you don't currently have one.

I tried that but I think that the market app is trying to get access through a cell network instead of the wifi....since there is not cellular hardware attached this results in an obvious error. I tried pandora as well (downloaded through a third party site). It installed but also had a network error. Could be a setting or maybe you android hackers have some work to do.

Im going to talk to dynavin tonight to see if it is something I am doing wrong or if it is in need of some software to redirect things through the wifi connection.
